Answer:
Always linear...
Decreases with successive trophic level
Answer:
Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases.An example of a simple food chain would be: A plant grows using the sun's energy and nutrients from the soil. A rabbit eats the plant. A fox eats the rabbit. The fox dies and decomposes into organisms that feed the soil.A producer, which is able to produce its own food, is also called an autotroph. Every species in the ecosystem relies on producers for their existence.A producer is able to covert inorganic compounds into organic compounds. Without this process life could not exist.A producer can use either solar energy or chemical energy to convert organisms into usable compounds.Because the sun is necessary for photosynthesis, life could not exist if the sun disappeared.Consumers can be carnivores (meat eater only), herbivore (plant eater only), omnivore (eats animals and plants), and a scavenger (eats dead animals).Examples of omnivores (plant and animal eaters) are bears (which eat fish, insects, honey, moose, and grass), turtles (which eat crayfish, earthworms, lettuce, and algae), squirrels (which eat seeds, fruit, eggs, and insects), and monkeys (which eat fruit, leaves, and frogs).Examples of carnivores (animal eaters) include hawks, snakes, foxes, and spiders.Examples of herbivores (plant eaters) include rabbits, moose, cows, groundhogs, and grasshoppers.Decomposers, which feed on dead animals, break down the organic compounds into simple nutrients that are returned to the soil. These are the simple nutrients that plants require to create organic compounds.It is estimated that there are more than 100,000 different decomposers in existence.Al-Jahiz was a 9th century scientist who is responsible for introducing the concept of food chains.The food web, which is a concept that expands on the food chain, was introduced in 1927 by Charles Elton.Food chains can be short, or they can be long, depending on how many consumers can be eaten before one dies and begins to decompose.If a food chain were to continue too long, the energy would become less and less and it would not be very valuable to the animal at the end.Step-by-step explanation:

Ana has a hypothesis that girls get up earlier and, as a result, usually enter Ana's Donut Shop before boys do. To
test her hypothesis, she spends 10 mornings asking the first 3 people to enter her shop whether they are a boy
or a girl.
The data she collects is given in the table below. "G" represents a girl, and "B" represents a boy.
Drag the bars to make a relative frequency plot that shows the proportion for each possible number of girls in
the first 3 customers in a day.

Step-by-step explanation:
The area of the full circle would be [tex]\pi *4^{2}[/tex], which is [tex]16\pi[/tex]
A full circle is 360 degrees. Since we are only taking a part of that, 135, we would put it in a fraction. [tex]\frac{135}{360}[/tex]
Last, multiply 16pi and 135/360 since we are taking a part of 16pi.
[tex]16\pi *\frac{135}{360}[/tex]
[tex]\frac{2160\pi}{360}[/tex]

f(3) = 12 for a geometric sequence that is defined
recursively by the formula f(n) = 0.5 ∙ f(n – 1), where
n is an integer and n > 0.
Write the equation in explicit form.
Answer:
[tex]f(n) = 96 * 0.5^n[/tex]
Step-by-step explanation:
Given
[tex]f(3) = 12[/tex]
[tex]f(n) = 0.5 * f(n-1)[/tex]
Required
Write as an explicit function
When n = 3, we have:
[tex]f(3) = 12[/tex]
[tex]f(3) = 0.5 * f(3-1)[/tex]
[tex]f(3) = 0.5 * f(2)[/tex]
Substitute: [tex]f(3) = 12[/tex]
[tex]12 = 0.5 * f(2)[/tex]
Solve for f(2)
[tex]f(2) = 12/0.5[/tex]
[tex]f(2) = 24[/tex]
So, we have;
[tex]f(3) = 12[/tex]
[tex]f(2) = 24[/tex]
Since it is a geometric sequence, calculate the common ratio (r)
[tex]r = \frac{f(3)}{f(2)}[/tex]
[tex]r = \frac{12}{24}[/tex]
[tex]r = 0.5[/tex]
Calculate the first term using:
[tex]r = \frac{f(2)}{f(1)}[/tex]
Solve for f(1)
[tex]f(1) = \frac{f(2)}{r}[/tex]
[tex]f(1) = \frac{24}{0.5}[/tex]
[tex]f(1) = 48[/tex]
The explicit function is then calculated as:
[tex]f(n) = f(1) * r^{n-1[/tex] ----nth term of a gp
[tex]f(n) = 48 * 0.5^{n-1[/tex]
Split the exponent
[tex]f(n) = 48 * \frac{0.5^n}{0.5^1}[/tex]
[tex]f(n) = 48 * \frac{0.5^n}{0.5}[/tex]
[tex]f(n) = 96 * 0.5^n[/tex]

Answer:
A reflection over the line y = x followed by a translation up 3 units
Step-by-step explanation:
Since this is a multiple choice question, let's test each answer out.
First scenario:
"A reflection over the y-axis followed by a translation right 3 units and down 4 units"
Reflect segment XY over the y-axis, we get segment XY between x = 2 and x = 6, on y = 5 line.Translate right 3 units, we get segment XY on y = 5 line, between x = 5 and x = 9.Translate down 4 units, we get segment XY on y = 1 line, between x = 5 and x = 9.Resulting segment does not match segment X'Y', this answer is incorrect
Second scenario:
"A reflection over the line y = x followed by a translation up 3 units"
Reflect segment XY over y = x line, we get segment XY, between y = -2 and y = -6, on x = 5 line.Translate up 3 units, we get segment XY on x = 5 line, between y = 1 and y = -3.Resulting segment matches segment X'Y', this is the correct answer.
Nick used his credit card to make several large purchases, and now owes the credit card company $4,273 plus 32% interest. His mother gave him $500 for his birthday. Which is the most responsible choice he can make regarding his birthday money?
A.
He can use all the money to pay down his credit card debt.
B.
He can invest $200 in the stock market and pay down his credit card debt with the rest.
C.
He can put $250 into a savings account that pays 3.8% interest and pay down his credit card debt with the rest.
D.
He can put all the birthday money in the 3.8% savings account.
Answer:
Step-by-step explanation:
A, because more debt would build up for your credit card if you added money to a savings account since you would have to wait a whole year to get interest back. And it wouldn't be B because it simply would not be worth it to invest in stocks while in debt. Also, I just took the test and got it right!
What is the measure of angle B in degrees?
Answer:
<B=119
Step-by-step explanation:
Each line of the triangle is straight, meaning they add up to 180. Additionally, all the angles of the triangle add up to 180. Using that, you can find the measure of each angle.
For <C;
180-112=68
So <C=68
For <A;
180-51-68=61
So <A=61
To make sure that all these angles add up correctly;
51+68+61=180
For <B;
180-61=119
So <B=119

This is how I would answer it, but there is an error with the question. The measure of the central angle of an arc is supposed to be equal to the length of the arc.

Step-by-step explanation:
Expand 4(6p-9)
=1+24p-36
Simplify 1+24p-36
=24p-35
Hope this helped!!!
Answer:
24p - 35
Step-by-step explanation:
1 + 4 ( 6p - 9 ) (multiply 4 x 6p = 24p and 4 x 9 = 36 )
1 + 24p - 36 ( subtract 1 on both sides on 1 and 36)
-1 -1 ( 36 - 1 = 35 )
24p - 35

If you're familiar with your times tables, you know that

The number 50 is between 49 and 64, so its square root is between √49=7 and √64=8.
